The Railroad’s Impact on Land Values in the Upper Great Plains at the Closing of the Frontier

We show that the impact of transportation improvements on land values is complex with a direct, positive relationship on the price of land and also a positive relationship with the ratio of improved acres to total acres, another important influence on the per acre price of land. We construct a two step estimation that removes the impact of transportation outlets on the ratio of improved to total acres before including the transportation variables and the adjusted ratio variable as independent variables in a regression on price per acre. This estimation gives us the expected positive impact of railroads on land price. We also use Box-Cox regressions to show the semi-log form, a common model specification, may be inappropriate for our data and possibly then for other land price research.Box-Cox, Railroads, Great Plains

Ruination

Ruination is a portion of a novel, set in Yucatán in 1923, that follows the romance of the state governor, Felipe Carrillo Puerto, and a visting journalist from the New York Times, Alma Reed, who is accompanying a delegation from the Carnegie Institute, which is bidding on a concession to excavate the Mayan ruins at Chichén Itzá. As governor, Felipe attempts to break the caste system of Yucatecan society and improve the lot of the impoverished Maya through land redistribution, education, women\u27s suffrage, and access to birth control. His plans bring him in conflict with the wealthy plantation owners and the Catholic Church. He also pursues a new divorce law that will allow him to end his marriage and wed Alma. He and Alma are caught up in late-stage spasm of the Mexican Revolution, an uprising that threatens their lives and their future

How PrEPped Are Our Providers?: Assessing Vermont Primary Care Providers’ Knowledge and Awareness of Pre-Exposure Prophylaxis (PrEP) Options for HIV Prevention

In recent years, a number of pre-exposure prophylaxis (PrEP) medications and dosing strategies have become available to patients to help prevent human immunodeficiency virus (HIV) infection. The primary objective of this research was to assess current PrEP awareness and prescribing practices of family medicine providers at the Hinesburg Family Medicine practice in Hinesburg, VT.https://scholarworks.uvm.edu/fmclerk/1769/thumbnail.jp

The labor injunction in Massachusetts

Thesis (M.A.)--Boston UniversityThe labor injunction has proven to be a very important means of control of labor in the United States. It is peculiarly American device in use, although its origins are in the English common law. The purpose of this undertaking is to trace the history and development of the labor injunction in its various aspects as it grew in Massachusetts. In addition to this accumulation of data some evaluation is attempted, although this is extremely difficult for lack of a norm

Movement demands and perceived wellness associated with preseason training camp in NCAA Division I college football players

The aims of this study were to examine the movement demands of preseason practice in National Collegiate Athletic Association Division I college football players using portable global positioning system (GPS) technology and to assess perceived wellness associated with preseason practice to determine whether GPS-derived variables from the preceding day influence perceived wellness the following day. Twenty-nine players were monitored using GPS receivers (Catapult Innovations, Melbourne, Australia) during 20 preseason practices. Individual observations (n = 550) were divided into offensive and defensive position groups. Movement variables including low-, medium-, high-intensity, and sprint distance, player load, and acceleration and deceleration distance were assessed. Perceived wellness ratings (n = 469) were examined using a questionnaire which assessed fatigue, soreness, sleep quality, sleep quantity, stress, and mood. A 1-way analysis of variance for positional movement demands and multilevel regressions for wellness measures were used, followed by post hoc testing to evaluate the relational significance between categorical outcomes of perceived wellness scores and movement variables. Results demonstrated significantly (p ≤ 0.05) greater total, high-intensity, and sprint distance, along with greater acceleration and deceleration distances for the defensive back and wide receiver position groups compared with their respective offensive and defensive counterparts. Significant (p ≤ 0.05) differences in movement variables were demonstrated for individuals who responded more or less favorably on each of the 6 factors of perceived wellness. Data from this study provide novel quantification of the position-specific physical demands and perceived wellness associated with college football preseason practice. Results support the use of position-specific training and individual monitoring of college football players

The positive predictive value of stroke identification by ambulance clinicians in North East England: a retrospective cohort study

Introduction/background Accurate prehospital identification of patients who had an acute stroke enables rapid conveyance to specialist units for time-dependent treatments such as thrombolysis and thrombectomy. Misidentification leads to patients who had a ‘stroke mimic’ (SM) being inappropriately triaged to specialist units. We evaluated the positive predictive value (PPV) of prehospital stroke identification by ambulance clinicians in the North East of England. Methods This service evaluation linked routinely collected records from a UK regional ambulance service identifying adults with any clinical impression of suspected stroke to diagnostic data from four National Health Service hospital trusts between 1 June 2013 and 31 May 2016. The reference standard for a confirmed stroke diagnosis was inclusion in Sentinel Stroke National Audit Programme data or a hospital diagnosis of stroke or transient ischaemic attack in Hospital Episode Statistics. PPV was calculated as a measure of diagnostic accuracy. Results Ambulance clinicians in North East England identified 5645 patients who had a suspected stroke (mean age 73.2 years, 48% male). At least one Face Arm Speech Test (FAST) symptom was documented for 93% of patients who had a suspected stroke but a positive FAST was only documented for 51%. Stroke, or transient ischaemic attack, was the final diagnosis for 3483 (62%) patients. SM (false positives) accounted for 38% of suspected strokes identified by ambulance clinicians and included a wide range of non-stroke diagnoses including infections, seizures and migraine. Discussion In this large multisite data set, identification of patients who had a stroke by ambulance clinicians had a PPV rate of 62% (95% CI 61 to 63). Most patients who had a suspected stroke had at least one FAST symptom, but failure to document a complete test was common. Training for stroke identification and SM rates need to be considered when planning service provision and capacity. http://dx.doi.org/10.1136/emermed-2019-208902.
